Why is Jim Carrey putting stuff in David Letterman’s mouth? (VIDEO)

You never can be too careful when it comes to your health, but we think Jim Carrey might be going a little overboard here.

Carrey was taking no chances when he dropped by the Late Show with David Letterman Wednesday night — after all, New York is a germ-ridden place and the talk-show host meets tons of people, all of who possibly could have Ebola. Obviously.

“Have you traveled abroad lately?” Carrey asked Letterman. “Have you ever kissed a monkey or licked an airport toilet seat?”

And (just in case): “Are you now or do you plan to be a member of ISIS?”

Letterman soon turned the tables. “You travel the world promoting the movies and such,” he said. “Are you worried about diseases?”

“Once you’ve done a couple of press tours, you know, you welcome death,” Carrey deadpanned. “You do, there’s nothing left that’s meaningful.”

Plus, “I’ve been married a couple of times,” he added, “so it takes a lot to scare me, Dave.”

Ironically, Carrey has a reputation for being an anti-vaxxer — perhaps the deeper level of comedy here is that he’s making fun of himself as well as society’s Ebola paranoia.
